Definitions
- the present invention relates to a method for preparing linear alpha-olefins (LAO).
- DE 43 38 414 C1 discloses a process for the oligomerization of ethylene to obtain linear alpha-olefins, wherein ethylene is catalytically converted in an empty tubular reactor utilizing a catalyst comprising a zirconium component and an aluminum component.
- the process is advantageously carried out in a continuous mode wherein gaseous and liquid outlet streams are obtained.
- the liquid outlet stream usually contains solvent, catalyst, dissolved ethylene and linear alpha-olefins.
- the catalyst may be preferably deactivated by caustic, although other quenching agents, such as water, alcohol or fatty acids, are known in the prior art.
- the deactivated catalyst is also extracted from the phase containing solvent, ethylene and alpha-olefins.
- HCl is formed which may catalyse isomerization of LAO which is not desired. Due to the presence of HCl high, but limited purities of the desired LAO products are obtained only. Further, the sensitivity of the oligomerization for an unintended runaway reaction is quite high. Additionally, the LAO products obtained only have a limited thermal stability. Moreover, side reactions in the oligomerization reactor and in the reactor outlet piping system can take place, such as fouling, plugging by traces of high molecular weight linear alpha-olefins, which may have impact on product qualities. In the catalyst deactivation and removal step further a limited mixing efficiency of linear alpha-olefins and caustic can be present.
- the object is achieved by a method for preparing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of solvent and homogenous catalyst, comprising the steps of:
- the amine is mixed with catalyst components prior to feeding the catalyst components into the oligomerization reactor.
- the amine is added continuously.
- the organic amine may be a primary, secondary, tertiary or cyclic amine.
- the organic amine is soluble in an organic phase containing linear alpha-olefins.
- the organic amine is insoluble or has a low solubility in water or a mixture of water and caustic.
- the organic amine may be preferably removed from the reactor outlet stream or one or more products by distillation, extraction or adsorption.
- the removed organic amine is recycled into the reactor and/or the reactor outlet piping system, preferably together with the solvent.
- the added amine may be dissolved in a solvent, preferably toluene or a linear alpha olefin fraction or a linear alpha olefin product.
- the amine is mixed in the reactor outlet piping system with the reactor outlet stream by means of a mixing device, preferably a static mixer, a dynamic mixer, an ultrasonic mixer or a ventury mixing nozzle.
- a mixing device preferably a static mixer, a dynamic mixer, an ultrasonic mixer or a ventury mixing nozzle.
- the amine is mixed with catalyst components prior to charging catalyst and amine into the oligomerization reactor.
- the catalyst is deactivated by caustic.
- the amine has a boiling point differing from the boiling point of the solvent utilized of not more than 20° C., preferably not more than 10° C., preferably not more than 5° C.
- the catalyst comprises a zirconium salt of organic acids and at least one organo aluminum compound.
- the zirconium salt has the formula ZrCl 4-m X m , wherein X ⁇ OCOR or OSO 3 R′ with R and R′ being independently alkyl, alkene or phenyl, and wherein 0 ⁇ m ⁇ 4.
- organic amine is added in an amount of 0.1 to 2.0 mol equivalent to chloride, preferably 0.5 to 1.0 mol equivalent to chloride.
- the at least one aluminum compound has the general formula R 1 n Al 3-n or Al 2 Y 3 R 1 3 , wherein R 1 represents an alkyl group having from 1 to 20 carbon atoms, Y represents Cl, Br or I, n is any number within the range 1 ⁇ n ⁇ 2.
- the organic amine is removed from the reactor outlet stream by distillation, extraction or adsorption and the removed organic amine is then recycled into the reactor and/or the reactor outlet piping system. Recycling can be preferably together with a solvent, but most preferably with a fraction of the LAO products, most preferably the C10-C12 fraction. Recovery and recycling of the dosed amine results in a significant improvement of the economics of the process, since the costs for the amine are reduced considerably. There are hardly any costs for an imported fresh amine, but only for a small make-up stream to cover any losses from the plant.
- organic amines are utilized which have a good solubility in the organic phase containing linear alpha-olefins, but have no or only a low solubility in water or a mixture of water and caustic.
- amines which include acidic groups are not suitable, e.g. amino-acids, monoethyl amine (MEA), diethyl amine (DEA), etc.
- Ethylene is oligomerized in a suitable reactor, for example an empty tubular reactor as disclosed in DE 43 38 414 C1, utilizing a catalyst comprising a zirconium component and an aluminum component.
- a suitable zirconium component is zirconium tetraisobutyrate
- a suitable aluminum component is ethyl aluminum sesquichloride.
- the oligomerization is carried out under conditions (temperature, pressure, etc.) known in the art. Ethylene, solvent and catalyst are introduced. From the reactor, a liquid organic outlet stream is discharged into a reactor outlet piping system containing solvent, for example toluene, catalyst, ethylene dissolved in the solvent, and linear alpha-olefins. This liquid organic outlet stream is transferred to a catalyst deactivation and removal section. The catalyst is deactivated by caustic and is removed from the outlet stream.
- the caustic phase may contain alkali metal hydroxide, preferably NaOH and/or KOH.
- the reactor comprises a feedline for feeding an organic amine into the oligomerization reactor and/or a feedline for feeding the organic amine into the reactor outlet piping system.
- the amine added can be mixed, e.g., with catalyst components outside of the oligomerization reactor and can then be fed mutually thereto. Additionally or alternatively, the amine added into the reactor outlet piping system can be mixed with the reactor outlet stream by means of a mixing device such as a static mixer, dynamic mixer, ultrasonic mixer or ventury mixing nozzle.
- the amines can be routed through the separation unit of the LAO plant for separating the linear alpha-olefins into separate fractions, end up in one or more products and are removed from the products e.g. by distillation, extraction or adsorption.
- the amine can be already removed from the reactor outlet stream prior to separation of the outlet stream into individual fractions, also by distillation, extraction or adsorption.
- the amine may be utilized in a once-through operation mode.
- the amines are recovered by any means (e.g. by distillation or extraction) and can be recycled to the oligomerization reactor or the reactor outlet piping system.
- a mixture of 3-ethyl-heptyl-amine and LAO's recycled from the separation section of an LAO plant is dosed into the LAO reactor outlet line.
- the dosing quantity is adjusted to achieve an amine concentration of 1000 wt ppm.
- the amine which has a boiling point between the C10 and C12 LAO products, is routed to the separation section of the LAO plant together with the total LAO fraction.
- the amine is removed from the LAO products by conventional distillation. Remaining traces of the amine in the C10 and C12 products will be removed by adequate adsorbers, depending on the required product specification.
- the production of a pure amine fraction is not required, since the amine is recycled to the LAO reactors, i.e. the recycled stream is a mixture of 3-ethyl-heptyl-amine and C10 and C12 LAO's.
- a small amine make-up stream from an amine storage vessel is fed into the amine system in order to compensate any amine losses.
- the separation section is provided to remove the amine from the LAO products, and, optionally, also already to provide a separation of the LAO product into separate fractions for further processing.
- the separation section is after the catalyst deactivation and removal step.
